Ok so, This is going to sound really stupid but I kow this was benneficial in th past and I have not tried this in 10 years but here's my question: I have two GPU's a 7970 and a 6970. Is their any bennefit to run both? Will having the 6970 plugged into the board allow the 7970 to use it's resources, or will it just be an unessesary power drain? Can it be used and for what bennefit?
